The True Workplace Violence Cost: A Seven-Tier Decomposition for Risk Leaders, CFOs, and Insurance Underwriters
A primary-source seven-tier decomposition of the true cost of a workplace violence incident, with empirical ranges from BLS, OSHA, NSC, NIOSH, and Liberty Mutual
The true workplace violence cost of a single serious incident is rarely the number that ends up in a regulatory filing or a press release. The public-record figure captures direct medical treatment for the injured employee, perhaps a regulatory fine, perhaps a published settlement. The number that lands in the operating P&L is two to four times larger, distributed across seven cost categories, and felt across three to five fiscal years. For risk leaders building the business case for AI physical security, that gap is the entire ROI conversation. Underestimate the true workplace violence cost and the security investment looks discretionary; capture the cost stack accurately and it becomes mandatory.
This report is a workplace violence cost decomposition: the full economic exposure of a serious incident across the seven cost categories finance reviewers actually scrutinize, with primary-source benchmarks from BLS, OSHA, the American Hospital Association, the National Safety Council, Liberty Mutual, and NIOSH. The cost stack is sector-agnostic in structure but sector-specific in inputs. The decomposition below supplies the empirical inputs to a CFO-grade four-variable ROI framework and the cost stack insurance underwriters increasingly model when pricing renewal terms.
The empirical scale of workplace violence cost in 2026
Each number does specific work. The 740 BLS workplace homicides anchors upper-tail incident cost; finance committees modeling expected cost over three to five years need the upper tail honestly populated. Liberty Mutual's $58.61 billion index anchors the steady-state cost of disabling injuries against the detection-relevant subset AI platforms can compress. The OSHA $afety Pays multiplier converts the visible cost (medical, indemnity) into true total operating impact.
The decomposition organizes those primary sources into seven cost tiers, each with empirical ranges and finance-defensible inputs. The structure is additive without overlap: each dollar of true cost lands in exactly one tier. That property makes it usable for board presentation, audit committee review, and broker conversation simultaneously.
Why cost decomposition is the foundation of the security business case
Workplace violence is the dominant cause of serious workplace injury in several industries and the dominant driver of the disabling-injury cost cohort AI physical security platforms address. The BLS Injuries, Illnesses, and Fatalities program tracks roughly 2.6 million nonfatal workplace injury cases per year, with assault and violent acts the leading cause of injuries requiring days away from work in healthcare and social assistance. BLS Census of Fatal Occupational Injuries data identifies workplace homicide as a top-five cause of fatal occupational injury annually, with retail trade, transportation, and healthcare in the higher-incidence cohorts.
Most security investment models compress the seven cost tiers into a single "cost of an incident" estimate. That compression is the modeling failure. A finance reviewer asked to approve a $200,000 platform cost against an unverified "$1M average incident" benchmark will challenge the benchmark; the same reviewer asked against a seven-tier decomposition with citations per tier will engage with the model. The decomposition also surfaces variance drivers: Tier 4 (litigation) is highly skewed, Tier 6 (retention) compounds for 12 to 36 months, Tier 7 (insurance) persists through multiple renewal cycles.
A finance committee will ask which costs are public and which are not
Publicly reported workplace violence costs typically capture only Tiers 1 and 4: direct medical and the published portion of litigation. Tiers 2 (productivity and operations), 3 (regulatory), 5 (security response and investigation), 6 (retention and recruiting), and 7 (insurance and program cost) almost never appear in the public record. Risk and finance leaders who model only the public-record tiers end up with a cost figure that runs 30% to 50% of the real operating impact. The seven-tier decomposition is built specifically to surface the tiers that exist in the P&L but not in the press release.
The seven-tier cost decomposition
The seven tiers below capture the full economic exposure of a serious incident, defined precisely so they do not overlap. The infographic shows typical proportional weighting; the depth sections walk through each tier with empirical benchmarks and the modeling errors finance teams catch most often.
Seven tiers of the true cost of a workplace violence incident
Proportional weighting based on BLS injury-cost research, OSHA $afety Pays multiplier, AHA hospital-sector data, and Liberty Mutual Workplace Safety Index.
Direct Medical & Immediate Response
Emergency treatment, transport, hospitalization, follow-up care; on-scene security and law enforcement response.
Productivity & Operational Disruption
Lost work time, replacement labor, unit shutdown, schedule disruption, peer-employee productivity drag.
Regulatory & Compliance Exposure
OSHA General Duty Clause citations, Joint Commission survey findings, state regulator action, audit cost.
Litigation & Settlement Exposure
Civil claims (negligent security, premises liability, employment), defense cost, settlement, judgment.
Security Response & Investigation
Internal investigation, external forensics, security program review, remediation engineering.
Retention & Recruiting Impact
Voluntary departures attributable to incident, replacement and onboarding cost, productivity ramp.
Insurance & Program Cost
Premium rate impact across GL, PL, WC, umbrella; deductible erosion; broker advisory; new program controls.
The proportional ranges above reflect typical distributions for a serious incident with employee injury. Lower-severity incidents skew toward Tiers 1, 2, and 5; fatality and critical-injury incidents skew toward Tiers 4, 6, and 7 because litigation, retention, and insurance compound for years after the event. The depth sections below cover each tier individually.
Tier 1: Direct medical and immediate response
Tier 1 is the most visible and the most familiar to risk teams. It captures emergency medical treatment for the injured employee or third party, ambulance transport, hospitalization, follow-up care, rehabilitation, and the immediate response cost of internal security and law enforcement. This is the tier that appears in workers' compensation loss runs, OSHA Form 300 logs, and the public-record portion of incident reporting.
Empirical range and modeling approach
The National Safety Council's Injury Facts places the average direct cost per medically consulted injury at approximately $44,000 across all causes, with assault and violent-act injuries skewing higher. For serious WV incidents involving hospitalization or surgery, direct Tier 1 cost ranges $30,000 to $150,000 per incident; fatal incidents shift the larger cost to Tiers 4 and 6.
The most common modeling error in Tier 1 is conflating direct medical cost with total cost, which under-represents true exposure by 60% to 80%.
Tier 1 is also the tier where AI detection produces the most directly observable severity compression. Detection-to-alert under 30 seconds and dispatch-to-arrival under two minutes consistently reduces injury severity. Each step down (fatal to critical, critical to hospitalization, hospitalization to outpatient) compresses Tier 1 cost by a factor of three to ten and compresses Tiers 4 and 6 by even larger factors.
Tier 2: Productivity and operational disruption
Tier 2 is the productivity drag created by an incident across the affected work unit. It includes the lost work time of the injured employee (captured separately from indemnity payments, which sit in workers' compensation), replacement labor cost, schedule disruption and overtime to backfill, the productivity drag on peer employees responding to and processing the incident, and any operational shutdown of the affected unit, ward, store, or facility.
Empirical range and modeling approach
BLS Survey of Occupational Injuries and Illnesses data places median days away from work for assault-related injury at approximately seven days across all industries, with healthcare workers averaging higher. NIOSH research and Integrated Benefits Institute (IBI) studies establish that productivity drag on the affected unit extends 30 to 90 days post-incident through reduced output, peer distraction, schedule disruption, and supervisor overhead.
The most common Tier 2 error is capturing only the injured employee's lost time. IBI full-burden methodology corrects: total productivity impact runs 1.5x to 2.5x the injured-employee lost time alone.
Operational shutdown is a discrete Tier 2 component worth modeling separately when triggered. A store closed for an afternoon following a robbery loses revenue at the daily-average rate net of variable cost; a manufacturing line shut down for an OSHA inspection loses gross-margin output at the line's hourly contribution rate; an ED in lockdown loses ambulatory capacity at the trauma-center reimbursement rate.
Tier 3: Regulatory and compliance exposure
Tier 3 captures the cost of regulatory and accreditation consequences of a workplace violence incident. The federal floor is OSHA, which enforces workplace violence under the General Duty Clause (Section 5(a)(1) of the Occupational Safety and Health Act of 1970) when a recognized hazard exists, the employer failed to address it with feasible means, and the hazard caused or was likely to cause serious harm. State analogs in California, New York, Washington, and other jurisdictions add specific workplace violence prevention program requirements with their own enforcement mechanisms.
Empirical range and modeling approach
The OSHA General Duty Clause citation framework is documented in 29 U.S.C. §654. Healthcare workplace violence has been a documented OSHA enforcement priority since the agency's Guidelines for Preventing Workplace Violence for Healthcare and Social Service Workers (Publication 3148) was reissued. OSHA serious-violation penalties currently cap at $16,131 per violation; willful or repeat violations cap at $161,323 per violation, both adjusted annually for inflation per the Federal Civil Penalties Inflation Adjustment Act. Joint Commission survey findings can produce remediation requirements valued in the high six figures or low seven figures for hospital deployments. The 2024 Joint Commission Workplace Violence Standards (NPG 2a) added explicit requirements for hospital workplace violence prevention programs.
The most common modeling error in Tier 3 is treating the headline citation as the full Tier 3 cost. Finance reviewers familiar with regulatory exposure model citation cost plus remediation cost plus legal-fee cost plus the operational time absorbed by the regulatory response. The full Tier 3 cost on a serious citation typically runs 4x to 8x the citation amount itself.
The Joint Commission's workplace violence standards (NPG 2a) added a Tier 3 channel for hospitals: failure to demonstrate documented WVPP during survey produces remediation requirements with their own cost stack. State mandates (California's SB 553; expanding state AI and security legislation) add jurisdiction-specific Tier 3 exposure.
Tier 4: Litigation and settlement exposure
Tier 4 is the most variable tier in absolute dollar terms and the tier finance reviewers scrutinize most closely. Most workplace violence incidents produce zero litigation cost; a small minority produce litigation cost in the seven-figure or eight-figure range. The expected value of Tier 4 is what matters in a multi-year cost decomposition, and it is what insurance underwriters increasingly model into rate-impact pricing.
Empirical range and modeling approach
WV litigation cost spans negligent security, premises liability, and employment claims. Defense cost alone for a serious negligent security claim typically runs $150,000 to $500,000 through trial preparation; settlement and judgment ranges extend from low six figures for non-injury incidents to mid-eight figures for fatality cases with documented foreseeability. ABA and RAND Institute for Civil Justice studies establish that defense cost runs roughly 30% to 50% of paid indemnity, providing a scaling factor.
The most common Tier 4 error is using a single-point estimate (often a high-profile published settlement) as expected value. Finance teams reject this as confusing tail risk with expected value. The defensible approach: P(litigation) times expected cost given litigation, with conservative inputs for both.
Foreseeability is what connects detection technology to Tier 4. Plaintiff arguments cite the availability of AI detection, the research base on detection-to-response compression, and peer-organization deployment patterns to establish that a serious outcome was foreseeable and feasible mitigation existed. Documented WVPP plus AI detection plus incident-rate trajectory toward zero produces the strongest defensive posture, which is also why underwriters factor detection technology into Tier 7 pricing.
Tier 5: Security response and investigation
Tier 5 captures the cost of internal investigation, external forensics, security program review, and remediation engineering following a serious incident. It is the tier most underestimated in pre-incident planning and the tier where AI detection produces the most measurable operational compression in the response phase.
Empirical range and modeling approach
Internal investigation cost includes security team time at fully loaded rates (BLS OEWS places median security supervisor wages at $52,000 to $68,000 annually; fully loaded cost runs 1.8x to 2.3x base wages), executive time (CSO, COO, GC, communications), and HR. External forensics, when triggered, runs $25,000 to $250,000 per incident.
The most common Tier 5 error is omitting executive time. The defensible approach captures executive hours during the active investigation window plus the multi-month tail of program review.
AI detection compresses Tier 5 in two ways. The detection event is documented with timestamp, camera, scene context, and confidence score, reducing investigation duration. Detection-driven incident-rate trajectory provides the empirical basis for program review findings, replacing retrospective analysis with quantitative trend data already in the alert history.
Tier 6: Retention and recruiting impact
Tier 6 is the most under-modeled tier in conventional incident-cost analyses and the tier that compounds longest. A serious workplace violence incident is consistently identified as a top-three voluntary departure driver in nursing, K-12 education, retail loss-prevention staff, manufacturing front-line, and several other workforce categories. Replacement cost is high and well-documented; the attribution share is empirically defensible from published exit-survey research.
Empirical range and modeling approach
The 2024 NSI Nursing Solutions National Healthcare Retention & RN Staffing Report places average RN turnover cost at $56,277 per departure with national hospital RN turnover at 18.4%. AONL and ENA violence-exposure surveys consistently identify WV as a top-three exit driver for bedside nurses, supporting attribution shares of 15% to 25% in WV-exposed environments. SHRM and Mercer research place general turnover cost at 50% to 200% of annual salary across industries.
The most common Tier 6 error is using a one-time replacement cost rather than the multi-year compounded effect. The right model captures cumulative excess turnover across the 12-to-36-month window.
The compounding nature of Tier 6 makes it the second-largest tier in many sector models. A 250-bed hospital with 600 RNs and an 18.4% baseline turnover, where a single ED incident depresses unit retention by an additional 3% for 18 months, produces 9 to 11 excess departures at roughly $56,000 each: a $500,000 to $620,000 Tier 6 figure from one incident. The Healthcare Workplace Violence AI Detection Playbook covers department-by-department dynamics.
Tier 7: Insurance and program cost
Tier 7 captures the multi-year insurance and program cost impact of a serious workplace violence incident. Carriers price renewals based on loss history, documented controls, and incident-rate trajectory; a serious incident appears in all three. The premium impact is the most durable component of the cost stack and the one most often ignored in conventional incident analyses because it materializes 6 to 24 months after the incident itself.
Empirical range and modeling approach
Workers' compensation experience modifiers are calculated under NCCI's three-year loss-history rolling window, so a single serious incident affects WC premium for three full renewal cycles. GL, property, and umbrella carriers use multi-year loss history plus documented-controls scoring; AM Best and the Insurance Information Institute publish industry rate-impact data. Carrier underwriting research increasingly factors AI detection and documented WVPP execution into rate scoring.
The most common Tier 7 error is treating insurance impact as a single-line item on one coverage. A serious incident affects GL, PL, WC, and umbrella simultaneously; modeling only one line understates true multi-line impact by 60% to 75%.
Tier 7 is where the insurance industry's focus on AI detection creates the strongest pre-incident value capture. Carriers writing healthcare, K-12, retail, hospitality, and manufacturing portfolios increasingly ask explicit questions about WV prevention technology in renewal questionnaires; the SAFETY Act Designation and Certification framework provides structural liability protection that carriers model into pricing.
How the seven-tier decomposition applies across operating sectors
The seven tiers are sector-agnostic in structure. What changes by sector is the proportional weighting, the dominant primary sources, and the operator-specific incident-rate inputs. The sector grid below summarizes the typical Tier-by-Tier weighting pattern in five major IntelliSee sectors.
Healthcare
Tiers 1, 2, and 6 dominate. Direct medical carries weight from nurse-on-patient and patient-on-staff assaults. Tier 2 compounds in ED and behavioral health. Retention (Tier 6) is the largest tier in many hospital stacks because of bedside RN replacement cost and the violence-exposure attribution from ENA and AONL research.
Retail & Hospitality
Tiers 1, 2, and 4 dominate. Robbery, employee assault, and organized retail crime drive Tiers 1 and 2; negligent security litigation (Tier 4) is a documented exposure in foreseeable-risk venues. The Retail Security Sector Playbook covers full sector economics.
Manufacturing & Warehouse
Tiers 1, 2, and 7 dominate. Severe injury cost is significant given the equipment context. Line shutdown carries gross-margin opportunity cost. Workers' compensation impact compounds across the three-year experience-modifier window. Manufacturing sector playbook covers operations detail.
K-12 Education
Tiers 3, 4, and 7 dominate in district-level stacks. Regulatory exposure is structural given state mandates and Title IX overlap. Litigation exposure is large because of foreseeability arguments and minor-plaintiff dynamics. The K-12 threat intelligence briefing covers incident pattern data.
Higher Education
Tiers 3, 4, 6, and 7 carry significant weight. Title IX, Clery Act, and state campus-safety mandates compound Tier 3. Resident-student plaintiff profile elevates Tier 4. The Higher Education Physical Security Playbook covers institutional dynamics.
Senior Living & Memory Care
Tiers 1, 2, and 6 dominate, with elopement, fall, and resident-on-resident incidents driving the stack. The Senior Living Fall Detection Standard of Care report covers operating-economics detail.
Five rules for a finance-defensible cost decomposition
The decomposition is most useful when paired with a small set of methodological rules that survive a finance committee review.
Rule 1: Apply the OSHA $afety Pays multiplier transparently. Show the direct-cost figure, the 2x to 4x multiplier, the source (OSHA $afety Pays, BLS injury-cost research, NSC Injury Facts), and the resulting total. The OSHA estimator is publicly accessible and finance teams can validate the methodology directly.
Rule 2: Capture all seven tiers, not just public-record ones. A decomposition capturing only Tiers 1 and 4 understates true cost by 50% to 70%. Tiers 2, 3, 5, 6, and 7 are real operating costs even when they never appear in any public document.
Rule 3: Model Tier 4 as expected value, not worst case. Single-event high-cost litigation is real but rare. The defensible approach treats Tier 4 as P(litigation) times expected cost given litigation. Finance committees reject worst-case framing as fear-based; they accept expected-value framing as standard practice.
Rule 4: Model Tiers 6 and 7 as multi-year compounded effects. A single incident affects retention for 12 to 36 months and premiums for 3 to 5 years. Build three-year and five-year scenarios with discount applied at organizational WACC, and present both NPV and the year-by-year accrual pattern.
Rule 5: Tie tier-specific reduction percentages to the compression evidence base. AI detection compresses Tiers 1, 2, and 5 most directly through severity reduction; affects Tiers 4 and 7 through documented controls; affects Tier 6 through cultural signal. Reductions should be tier-specific, with peer-reviewed citations for any rate above 15%.
Cost-decomposition modeling errors and their corrections
| Modeling Error | Why It Fails Finance Review | Corrected Approach |
|---|---|---|
| Single-line "cost of an incident" | Compresses seven tiers into one number; under-represents true exposure by 50–70% | Seven-tier decomposition with citation per tier and transparent multiplier |
| Direct medical only (Tier 1 only) | Captures 10–18% of true cost stack; ignores larger tiers | Apply OSHA 2x–4x indirect multiplier with source citation |
| Worst-case Tier 4 framing | Treats tail event as median case; finance teams reject as fear-based | Probability-weighted expected value with conservative P(litigation) and cost inputs |
| One-time Tier 6 estimate | Misses 12–36 month compounding; understates retention impact materially | Multi-year cumulative model with attribution share from exit-survey research |
| Single-line Tier 7 impact | Misses cross-line effect on GL, PL, WC, umbrella simultaneously | Sum across all affected coverage lines with broker validation across renewals |
| Public-record-only modeling | Captures roughly 30–50% of the seven tiers; ignores operating-only tiers | All seven tiers with public-record subset shown separately for transparency |
| Sector-agnostic input ranges | Healthcare and manufacturing have different tier weightings; uniform inputs distort | Sector-specific weighting with operator-specific incident-rate data where available |
How AI detection compresses the cost stack
AI detection does not eliminate workplace violence cost; it compresses the stack across the tiers it can affect, by changing the time-to-response distribution and improving the documentation quality that affects Tiers 3, 4, and 7.
Tier 1 compresses through severity reduction: when a drawn weapon is detected and a charge nurse is alerted within 30 seconds, the incident trajectory shifts toward de-escalation, security positioning, or law-enforcement intercept before injury rather than after. Tier 2 compresses through the same mechanism plus reduced unit shutdown. Tier 5 compresses through automated incident documentation that would otherwise require extensive retrospective forensic work.
Tiers 3, 4, and 7 compress through documented controls. OSHA General Duty Clause defense is materially stronger with documented WVPP plus AI detection plus incident-rate trajectory. Plaintiff foreseeability arguments are materially harder with documented detection coverage and a defensible response time profile. Carrier renewal scoring improves when controls show in the questionnaire and loss history validates the assumption.
Tier 6 compresses through the cultural signal documented detection sends to the workforce. Bedside nurses, teachers, retail staff, and manufacturing supervisors consistently identify visible safety investment as a top-three retention factor in post-incident surveys. The absence of facial recognition or stored video, plus alert routing into existing dispatch workflows, keeps the signal positive rather than surveillance-coded.
Different platform architectures compress different tiers
The vendor landscape includes platforms with different architectural choices. Some, like ZeroEyes, use trained-veteran human verification with RapidSOS first-responder integration as a core part of the detection-to-dispatch pipeline; others rely on automated alerting into the customer's existing response workflow. Both architectures compress the cost stack; the right comparison criterion is which compression profile fits the organization's existing operational infrastructure. Buyers should evaluate the detection-to-response compression evidence on each tier (T1, T2, T5 most directly; T3, T4, T7 through documented controls; T6 through cultural signal) rather than architectural philosophy.
The IntelliSee platform was architected for breadth specifically because the decomposition rewards it. Single-modality platforms hit a subset of tiers strongly; multi-modality platforms compress all seven from a single integration footprint. The platform runs object, posture, motion-pattern, and zone-violation detection on a unified appliance with shared alert routing into existing dispatch consoles, RapidSOS first-responder integration, and the customer's own VMS. No facial recognition, no stored video, no PHI collection. DHS SAFETY Act Designation provides the structural liability protection that strengthens Tier 7 modeling.
Translating the decomposition into a board-ready model
Risk and finance leaders ready to bring the seven-tier decomposition into a board or audit-committee review typically follow a three-step modeling sequence.
Step one: gather operator-specific data per tier. Tier 1: workers' compensation loss runs, medical claims, OSHA Form 300 logs. Tier 2: BLS days-away methodology, supervisor time logs, schedule-disruption records. Tier 3: prior OSHA citation history, accreditation findings. Tier 4: prior litigation history, broker claims database, defense panel benchmarks. Tier 5: prior investigation cost records. Tier 6: voluntary turnover segmented by role and exit reason, NSI / AONL benchmarks. Tier 7: current annual premiums by coverage line, prior renewal trajectory, broker advisory.
Step two: populate each tier with conservative inputs. Apply the OSHA $afety Pays multiplier transparently. Use lower-bound benchmarks where operator data is unavailable. Apply tier-specific reduction percentages tied to detection-to-response compression evidence. Sum the seven tiers to total expected operating cost.
Step three: model multi-year scenarios with discount. Build a three-year base case capturing Tiers 1, 2, 3, 5 plus the early portion of Tiers 6 and 7; a five-year stretched case capturing Tier 4 resolution timelines and full Tiers 6 and 7 compounding. Discount at organizational WACC or hurdle rate. Present expected operating cost, expected detection-driven reduction, and net implied platform value. The implied value is the empirical input to the four-variable ROI framework Variable 1 calculation, sanity-checked via the ROI calculator for a first-pass estimate.
Frequently asked questions about workplace violence cost decomposition
What is the typical total cost of a serious workplace violence incident in healthcare?
For a community hospital incident with an injured staff member, the seven-tier decomposition typically totals between $250,000 and $1.5 million across the three-to-five-year tail. Direct medical (Tier 1) runs $30,000 to $150,000; productivity disruption (Tier 2), litigation exposure (Tier 4), retention impact (Tier 6), and insurance premium impact (Tier 7) can each individually exceed Tier 1. Fatal incidents and incidents with documented foreseeability run materially higher because Tiers 4 and 6 dominate.
How do I apply the OSHA $afety Pays multiplier in a finance-defensible way?
Show the direct cost (Tiers 1 and 5) explicitly, then apply the 2x to 4x indirect-cost multiplier with citation to OSHA $afety Pays, BLS injury-cost research, or NSC Injury Facts. The multiplier is established federal methodology that finance teams can validate directly. The most common error is hiding the multiplier inside a single per-incident benchmark.
Is Tier 4 litigation exposure overstated for organizations without prior workplace violence litigation history?
Tier 4 should be modeled as probability-weighted expected value, not a deterministic figure. Organizations without prior history use the sector-level base rate combined with primary-source defense and settlement ranges. The plaintiff bar's increasing foreseeability focus combined with the documented availability of detection technology means historical rates are a floor, not a ceiling. Organizations should engage outside counsel and broker to validate inputs.
How do I model Tier 7 insurance impact when carriers do not promise specific premium credits?
Tier 7 is modeled as a 36-to-60-month rolling expected value. Engage the broker pre-deployment, document the specific risk-mitigation factors carriers value (program documentation, detection technology architecture, incident-rate trajectory, SAFETY Act protection where applicable), and treat Tier 7 as a multi-year directional factor across affected coverage lines rather than a guaranteed first-year credit.
Does Tier 6 retention impact apply equally across sectors?
Structurally yes; empirical inputs differ. Healthcare nursing has the most complete research base (NSI, AONL, ENA). K-12 teacher data comes from NCES and Learning Policy Institute. Manufacturing turnover comes from BLS JOLTS. Conservative attribution shares of 10% to 15% are broadly defensible without internal data; higher shares require exit-survey or pre/post incident analysis support.
How long should a multi-year cost-decomposition model run?
Three to five years is typical. Three-year models capture immediate-period tiers plus early Tier 6 and Tier 7 effects. Five-year models capture Tier 4 resolution timelines, the full Tier 6 compounding window, and the Tier 7 renewal-cycle impact. Boards generally accept three-year payback; five-year NPV is the defensible secondary metric.
Where does the seven-tier decomposition fit relative to the four-variable ROI framework?
The decomposition supplies inputs to Variable 1 of the four-variable framework. The framework is the methodology layer (incident avoidance, retention, insurance, security efficiency); the decomposition is the cost-stack reality that populates the incident-avoidance variable. Variables 2, 3, and 4 draw from separate research bases.
